Will Apollo footprints fade?
Robinson estimates that these impacts occur at more than 33,000 mph (53,000 kph). These collisions will eventually wear down the tracks and objects left at the landing sites, he explained. “Slowly over time, first the tracks will disappear — they will all be ground into and mixed into the soil,” Robinson said.
How long do footprints stay on the moon?
a million years
An astronaut’s footprint can last a million years on the surface of the moon. It may have been decades since we last set foot on the moon, but its surface is still marked with the historic footprints of the 12 astronauts who stomped across it. That’s because the moon has no atmosphere.

How long will it take to travel to Mars?
The three profiles considered here are: 1) The Short-Stay Mission- often referred to as an opposition-class mission, this mission profile provides Mars stay times of 30 to 90 days with a round trip total time of 400 to 650 days.
What are the risks of the Mars mission?
2) In-space Environment – this segment of the mission is composed of the time spent by the crew in transit to Mars and on return to Earth. While essentially uneventful, this in-transit travel time poses the next greatest risk to crew safety due to radiation exposure and zero-g.
Which transit trajectory is best for a crewed mission to Mars?
From the comparison of the considered mission profiles, it is clear that the Long-Stay fast transit trajectory is both the safest and most productive option for a crewed mission to Mars. A comparision of the 3 mission profiles can be seen here…
